摘　　要：本文提出一种流线与等涡量线交替迭代的方法,用来计算速度剖面为折线的来流绕圆柱体的无分离流动。算例结果说明该方法可行。In the paper, an iteration method is presented to calculate the steady flow field without separation of the stream with pieciwise linear continuous velocity profile past a circular cylinder. In each iterative step, streamlines of last step result are considered as equivorticity line to determine the new flow field. The iterative process is stopped when convergence is obtained. Several examples are given. The calculation shows that the method is efficient.

关 键 词：圆柱体 非均匀来流 定常流动 迭代
